Problem: A system must have a reliability of 99%. How many components are required in parallel when each component has a reliability of 65%?

Solution Preview

When a system is in parallel, this means that the system is work as long as at least one component is working. It is easier to think that the system fails when all parts fails.

Since the components are independent, for a system with n components, we have

P(system ...

Solution Summary

Compute a System Reliability at 65%. How many components are required in parallel?

A parallel RL circuit has the values, R = 5kohms and XL = 5kohms. A voltage source of Vt = 10Vrms is connected in parallel to R and L. Determine the total current, delivered by the voltage source Vt.

1. Failure rate for item A is 0.002 failures/hr., item B is 0.0003 failures/hr. and item C is 0.001 failures/hr. The componentsare serially related with independent failure modes. What is the system reliability at 55 hrs? Please round your answer to 3 decimals.

A school is being designed with three identical building-wide fire alarm systems. The reliability of each fire alarm systems is 0.995.
a. Should the fire alarm systems be placed in series, parallel, or in a series-parallel combination?
b. Defend you recommendation using a system reliability analysis.

Suppose the government mandated gasoline prices to remain constant at $4.26 per gallon everywhere across the country, restricting gas stations from increasing the price in the future. The law will take effect in 2012.
Is there an equation that would illustrate the price of gas under the new law? Is there an equation that i
